Question

.I went to a store and spent 1/3 of my money and P5.00 more. Then, I went to a second store where I spent 3/5 of my remaining money plus P9.00 more. I had exactly P45.00 left. How much money had I at first?

Answer 1

m - m/3 - 5 - 3/5(m - m/3 - 5) - 9 = 45

m - m/3 - 3m/5 + m/5 = 56

15m - 5m - 9m + 3m = 840
